The Spitzer/IRAC view of black hole - bulge scaling relations
E. Sani, A. Marconi, L. K. Hunt +1
We present a mid-IR investigation of the scaling relations between supermassive black hole masses (MBH) and the structural parameters of the host spheroids in local galaxies. The w…
The far-infrared view of M87 as seen by the Herschel Space Observatory
M. Baes, M. Clemens, E. M. Xilouris +29
The origin of the far-infrared emission from the nearby radio galaxy M87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emissio…
Testing models for molecular gas formation in galaxies: hydrostatic pressure or gas and dust shielding?
Michele Fumagalli, Mark R. Krumholz, Leslie K. Hunt
Stars in galaxies form in giant molecular clouds that coalesce when the atomic hydrogen is converted into molecules. There are currently two dominant models for what property of th…
A decline and fall in the future of Italian Astronomy?
Angelo Antonelli, Vincenzo Antonuccio-Delogu, Andrea Baruffolo +89
On May 27th 2010, the Italian astronomical community learned with concern that the National Institute for Astrophysics (INAF) was going to be suppressed, and that its employees wer…
The Spitzer View of Low-Metallicity Star Formation: III. Fine Structure Lines, Aromatic Features, and Molecules
Leslie K. Hunt, Trinh X. Thuan, Yuri I. Izotov +1
We present low- and high-resolution Spitzer/IRS spectra, supplemented by IRAC and MIPS measurements, of 22 blue compact dwarf (BCD) galaxies. The BCD sample spans a wide range in o…
